Synthesis, Structures And Properties Of M₁/M₂/I Heterometallic Hybrid Polymers Constructed By Bidentate Conjugated Organic Ligands

M/I hybrid polymers have combined the advantages of organic, inorganic andnanometer materials, and captured the great interests of chemists because of theirwide application value in multitudinous fields such as photoconductivecommunication, photoluminescence and thermoluminescence nonlinear optical swith,photoluminescence and electroluminescence optoelectronic materials, field effecttransistor and so on. In addition, recent studies show that they also exhibit attractiveprospect in terms of application of photovoltaic materials.In this work, we have carried out controllable synthesis research on heterometalliciodide hybrid polymers on the basis of studying systematically existing achievementsat home and abroad, and successfully synthesized seven heterometallic iodide hybridpolymers with novel structures by introducing other metal ions (Ag+, Pb2+, Bi3+)which have coordinated firstly with bidentate nitrogen-containing conjugated organicligands in M/I system (complexes1～7). Complexes1～5are heterometallicpolymers including M/Ag/I inorganic framework, in which the second metal ion (suchas Cu2+, Pb2+, Bi3+) connects directly with [AgxIy](y-x)-inorganic chain (or cluster).Thereinto, hybrid polymers including three Cu(II)/Ag/I inorganic frameworks havenever been reported previously; In complexes6～7, the second metal ion (Cu2+andNd3+) doesn′t connect directly with Pb(Bi)/I inorganic chains, but associating togetherby electrostatic attraction, and forming [M′Ln]·[MxIy] type hybrid polymers includingsingle metal polyanion structures; At the same time, we also make bidentateconjugated organic ligands interact directly with single metal iodides (such as PbI2,BiI3, CuI, CdI2), and get five superamolecular hybrid polymers with novel structures.We aim to investigate the impact on heterometallic inorganic framwork byintroducing the second metal complex cation in Ag(Pb, Bi)/I at the molecular level,and reveal the relationship between structure and property, which will make somebasic research work for discovering new materials such as semi-conductor, non-linearmaterials, magnetic materials, photovoltaic materials and so on.
